Progesterone and its analogs may exert opposite effects on cell proliferation, apoptosis, and epithelial-mesenchymal transition, leading to higher cell motility and metastasis. Their ultimate effect is determined by a number of factors: the structure and concentration of the steroid, its affinity for various forms of steroid hormone receptors ...

The history of progesterone and hormone replacement therapy goes back to 1934 when Butenandt obtained crystalline progesterone and Kaufmann started to treat ovariectomized women with both estrogens and progesterone (Table 1). Today synthetic perorally active 19-nortestosterone and 17-alpha-hydroxyprogesterone derivatives are used in addition to ...

Progestin implants for contraception are highly effective, safe, and the most convenient choice for many women. Progestin implants currently on the market, preparing for launch, or under investigation are reviewed here. Their basic galenic and pharmacokinetic features, as well as their contraceptive effectiveness, are described.

Classification and pharmacology of progestins
Maturitas, 2003Besides the natural progestin, progesterone, there are different classes of progestins, such as retroprogesterone (i.e. dydrogesterone), progesterone derivatives (i.e. medrogestone) 17alpha-hydroxyprogesterone derivatives (i.e. chlormadinone acetate, cyproterone acetate, medroxyprogesterone acetate, megestrol acetate), 19-norprogesterone derivatives (i.

The androgenicity of progestins
The American Journal of Medicine, 1995All steroid hormones are structurally similar, but relatively minor differences cause profound alterations in biochemical activity. The 21-carbon series (pregnane nucleus) includes the corticoids and the true progestins (e.g., medroxyprogesterone acetate).

While the benefits of progestin use in hormone replacement therapy (HRT) are well recognised as far as endometrial protection is concerned, their risks and drawbacks have generated controversial articles. The data related to the progestin effect on breast tissue has been interpreted differently from country to country. However it has been admitted that,

Contraception, 2001
There is considerable confusion concerning the use of the term "progestin" in referring to progestational compounds. Such term is often restricted to progestational agents that are synthetic and excludes progesterone which is a natural compound. In 1930 when progesterone had not yet been isolated the term "progestin" was proposed for the name of this
